Medical Nutrition Therapy in Prediabetes
Study | Population | Treatment goal | Treatment strategy (interventional group) | Findings |
---|---|---|---|---|
IGT (2-h plasma glucose 7.8 ± 11.0 mmol/l) BMI > 25 kg/m2 (overweight) | To delay development of type 2 diabetes in high-risk individuals with IGT, at least as long as the intervention prevents 5% weight loss or BMI < 25 kg/m2 or weight loss of 5–10 kg depending on the degree of obesity | Dietary strategy: Carbohydrates: 50% of daily calories Saturated fats: 10% of daily calories Mono and polyunsaturated fats: 20% of daily calories Cholesterol: < 300 mg/day Dietary fiber to 15 g per 1000 kcal or more Physical activity: 30 min/day or more | Compared with control group 3% reduction in the relative risk of developing type 2 diabetes was observed in the intervention group | |
Diabetes Prevention Programme [39] | IGT (2-h plasma glucose 140–199 mg/dl based on 75-g OGTT) BMI > 24 kg/m2 (> 22 kg/m2 among Asian Americans) | To delay development of type 2 diabetes in high-risk individuals with IGT 7% weight loss in first 6 months and maintenance of weight loss throughout the study | Dietary strategy: Individual based (individual model of treatment) Initial phase—to reduce total fat rather than calories, overall healthy eating Later phase—calorie balance: restrict calories and fat To achieve 1–2 lb/week weight loss Physical activity: 150 min/week of moderate physical activity (700 kcal/week expenditure) | Lifetime intervention resulted in 58% reduction in the incidence rate of diabetes |
Confirmed type 2 diabetes BMI ≥ 25 kg/m2 (≥ 27 kg/m2 in patients taking insulin) | To achieve and maintain (long term: up to 11.5 years) weight loss in patients with type 2 diabetes to reduce cardiovascular morbidity and mortality 7% weight loss in first year | Dietary strategy: Similar to Finnish Diabetes Prevention study Initial phase—portion control diet containing food with fixed calorie and macronutrient content Later phase—diet modifications depending upon individual weights Physical activity: 175 min/week moderate physical activity | At 1 year, lifetime intervention group lost 8.6% of their initial body weight while the DSE group lost 0.7%. At study end, lifetime intervention group had a 6% weight loss while DSE had 3.5%. With regard to fitness, lifetime intervention had greater improvement in heart rate recovery after graded exercise testing compared with DSE |
